What is a prosthetic eye motility peg?

A prosthetic eye motility peg, also known as an orbital implant, is a medical device used in patients who have lost an eye due to trauma, disease, or surgery.

The motility peg is a small, cone-shaped peg that is surgically implanted into the socket of the missing eye. It serves two main purposes: to provide support for the prosthetic eye, and to allow the prosthetic eye to move in a natural, lifelike manner.

The motility peg is typically made of a biocompatible material, such as silicone, and is carefully shaped to fit the individual patient's socket. During the surgical implantation process, the peg is placed into the socket and secured in place with small screws. Once the motility peg is in place, the prosthetic eye can be attached to it using a special attachment mechanism.

The motility peg allows the prosthetic eye to move in a way that is similar to a natural eye. This is because the peg is designed to mimic the movement of the extraocular muscles, the muscles that control the movement of the eyes. By allowing the prosthetic eye to move in a natural manner, the motility peg helps to restore the patient's ability to move their eyes in a coordinated way, improving their overall quality of life.

In addition to providing support for the prosthetic eye and allowing it to move in a natural way, the motility peg also helps to prevent the socket from collapsing, which can happen when an eye is lost. This is because the peg provides structural support for the socket, preventing it from collapsing and helping to maintain the shape of the socket.

In conclusion, a prosthetic eye motility peg is a small, cone-shaped device that is surgically implanted into the socket of a missing eye. It provides support for the prosthetic eye and allows it to move in a natural, lifelike manner, helping to restore the patient's ability to move their eyes in a coordinated way and improving their overall quality of life.
